Can Haiwei m+ and Runbaiyan Black Gold be interchanged?

You can't. Haiwei m+ and Runbaiyan Black Gold are both cost-effective hyaluronic acid injections, which are filled in chin, rhinoplasty and nasal bottom, but the same brand is used in the same parts. Hyaluronic acid, also known as hyaluronic acid, is a natural polysaccharide colloidal substance, which has a good function of storing water and liquid.
